The Lowdown
Righto, let’s talk about what’s headed our way at Jaconé. We’ve got a solid run of south swell coming through, but it’s a bit of a mixed bag with the winds, so you gotta pick your moments.
The first proper option kicks off Tuesday, August 11th. Tuesday morning is a bit average with a cross-shore breeze, but the swell is already building at 8ft, period 13 seconds, and a combined energy of 2332 (moderate). It’s a bit sloppy though. The real highlight is Tuesday afternoon: a clean 10ft S swell at 13 seconds, with light cross-offshore winds. This one has serious energy (3059 – moderate) but it’s a big wave. At over 8ft, this is only for the experts. It’s consistent here, so you’ll get plenty of waves, but expect some company – crowds are sometimes an issue. The water temp is about average for the time of year.
Wednesday, August 12th morning is a gem. Offshore wind from the ENE at only 10 km/h, clean conditions, and a 8ft S swell with a 12-second period. Energy is still solid at 1523. This is excellent for experienced surfers. The afternoon gets a bit blown out with stronger cross-off winds.
Thursday, August 13th and Friday, August 14th mornings are both clean with light offshore winds. Swell sits around 7ft to 7ft, 12-13 seconds, energy in the 1300-1500 range. Again, this is territory for competent surfers only – the size keeps it from being beginner-friendly. Saturdays and Sundays ease down in size but stay clean in the mornings.
Now, the standout sessions. I’d say the absolute best on offer is Tuesday afternoon (August 11th), even though it’s big, because it’s clean and has the most size and power. The second best is Wednesday morning (August 12th) – offshore, clean, and still plenty of punch. After Sunday, the swell drops right off into a flat spell from around the 17th to the 24th, with only small, weak, or messy waves. There’s a bit of a lull for over a week.
But hold on – there’s a promising uptick right at the end. On Tuesday, August 25th morning, we’ve got glassy conditions, a 5ft S swell with a very long 16-second period, and combined energy of 1168. That long period means well-shaped, powerful waves, best handled at a point or reef – this setup is excellent for experienced surfers. It’s a long way out, so take it as a promising look. Then Wednesday, August 26th morning brings offshore winds again with 7ft S swell at 14 seconds and energy jumping to 2174 – another standout potential for experts, but it’s even further off.
If you’re an experienced surfer, you’ve got a few days to really get after it. Beginners should steer clear of the big stuff and keep an eye on the first week of September forecasts.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
